I was looking to check-shove the turn because I think his flop calling range is really wide and my T’s will be good often enough but if I check-call I’ll be in a bad spot on river. Given that the turn checked through and the river was another overcard to my pair (and AK got there), I don’t think I can expect to be called by worse if I bet.
I was intending to check-call the river but his overbet threw me off. On the one hand, it makes no sense for him to have a straight, but a lot of guys just don’t overbet the river without a monster. There was an outside chance he rivered a set (or slowplayed one, which I guess makes more sense except that it’s odd he would then overbet it). I tanked down to one second left, mostly because I was on a bunch of other tables, and finally made a kind of impulsive call.
Why does it make no sense for him to have a straight? Because he would have 4 bet AK pre-flop or because he bets the turn once you check? Certainly seems plausible that AK with position might just call you on the flop.
You’re right that it’s not inconceivable but I think he’s usually 4-betting preflop and of the times that he doesn’t he’s sometimes betting turn.
